With more than 90 games of preseason complete, the average team is taking 25.1 three-pointers per game, up from 21.8 last preseason, which represents a 15 percent surge. 

During the 14-15 regular season, teams shot 22.4 three-pointers per game.

Preseason rates have mirrored regular season rates dating back to 10-11 when RealGM began preseason tracking.

The 04-05 Phoenix Suns attempted an average of 24.7 three-pointers per game, which easily led the NBA. The average team is now shooting more than that.

"This preseason right now, everybody's playing with space and everybody's playing fast," Erik Spoelstra said. "The first open 3, people are taking it."

"If you look at trends in this league, 3-point shooting percentage was the No. 1 factor in why teams won," Steve Clifford said. "The five best 3-point shooting teams were the four teams who played in the conference finals and then the Clippers. All five of them were top 10 all-time in the NBA. That's the way this league has gone."
